Ethnicity and Policing in the Global South: Descriptive Representation and Expectations of Police Bias

City residents in the Global South commonly encounter the police. Yet, outside of established democracies, we know little about how ethnicity shapes everyday policing in diverse urban contexts. Existing approaches generate competing expectations, with some arguing that officers are more rather than less discriminatory towards coethnics. We test these theories through a survey experiment conducted in Karachi, Pakistan-one of the world's largest megacities. We find that civilians are only marginally less likely to expect procedural justice from non-coethnic officers, even in a context where ethnicity is highly salient. However, suggestive evidence indicates that this small effect is significantly magnified for respondents who perceive their group to be underrepresented in the police. Descriptive representation is therefore a powerful moderator of the relationship between ethnicity and expectations of police bias. These results have implications for the development of effective and legitimate police institutions in weakly institutionalized contexts.
